Subject: [PATCH] dt: Create static regulators and clocks for camera
|
|
nodes
|
|
|
|
Unloading regulators through dynamic device tree doesn't work
|
|
as the regulators will unregister whilst clients are still
|
|
registered. Whilst the regulator framework does WARN when that
|
|
happens, the client putting the regulator then typically results
|
|
in a NULL dereference and badness.
|
|
|
|
Instead of creating regulators and clocks from the overlays,
|
|
create regulators and clocks for the sensors in the base DT.
|
|
